Abstract
Articles that are oleophobic and/or hydrophobic, as well as associated methods, are generally provided. In some embodiments, articles described herein do not comprise fluorinated polymers. Articles described herein may comprise nanostructures that contribute to their hydrophobicity and/or their oleophobicity. Articles described herein may have high wash resistance.
Claims27
An article, comprising:
- a substrate comprising a surface, wherein the substrate comprises a textile;
- a plurality of nanostructures comprising a polymer on the surface of the substrate;
- and
- a layer comprising a polymerized silane and/or a polymerized siloxane, wherein the layer covers at least a portion of the surface and at least a portion of the plurality of nanostructures, and
- wherein a surface of the article is hydrophobic and/or oleophobic.

A method of forming an article, comprising:
- forming a first layer comprising a polymer on a surface of a substrate by exposing the surface of the substrate to a first plasma comprising a monomer;
- etching the first layer by exposing the first layer to a second plasma to form an etched first layer;
- and
- forming a second layer comprising a polymerized silane and/or a polymerized siloxane on the etched first layer.
1 more element
A method of forming an article, comprising:
- forming a layer comprising a polymer on a surface of a textile by exposing the surface of the textile to a first plasma comprising ethylene, butadiene, acetylene, methane, methanol, ethanol, or a combination thereof;
- and
- etching the layer using a second plasma comprising oxygen, argon, helium, neon, krypton, xenon, or a combination thereof.
